Collaborative EW

The trend to Collaborative EW is surely pushed by the proliferation of unmanned platforms and their “collaboration” with manned platforms in the manned-unmanned teaming (MUT), but it implies also a multiple layer collaboration: Stand-Off/Stand-In collaboration, Sensor collaboration, Man-Machine Collaboration, blue on blue collaboration/interoperability.

Applying collaborative EW and SIGINT functions in such cases means:

  • • Subdivide the whole function in sub-functions that could be realized in small payloads
    • Be able to coordinate the platforms in a way to reconstruct the whole from its components
    • Count on a communication infrastructure which has to be solid, trusted and capable to manage synchronization of data gathered using different platforms
    • Plan the mission according to platform endurance
    Operational implications refer to:
    • Command and Control and Decision Making Process
    • Mission planning for distributed tasks
    • Reconfiguration during mission
    • Multi-domain distribution (time-frequency-space) of sensors and effectors
    • Cyber resilience

In the near future the new role of EW assets evolves in “Collaborative EW” based on net-centric architecture needed to ensure the coordination of assets, expertise, knowledge and tools in order to integrate EW systems in the platform and across the cooperating platforms.
Modern EW operations suggest the definition of an EW layer in which the Information Management Organization collapses into a Command & Control Information structure.
This is not only a high-level change but also a technological challenge for all the Countries and Industries involved in the field.
To this respect the network is the force multiplier and the future objective is collaborative “knowledge sharing”.
A modular and flexible architecture can meet emerging needs and support open interfaces to enable integration and interoperability into a really modular and high-performance EMSO solution, for Radar and Communications Surveillance-Reconnaissance and Electronic Attack.

• EW mission support
A powerful EW Operational System (EWOS) that exploits a mission support methodology, including Concurrent Planning, supports the Cooperative EW and the network-centric capability.
The planning is not only function of the foreseen scenario but takes into account the presence of several platforms in a package, so the mutual position of the platforms and the Radio Link Coverage will be primary parameters that will evolve dynamically during the mission.

Figure 1: Concurrent MDP

The Mission Data Planner (MDP) will be modular, dynamic and flexible self-adapting to the mission phase and to the main parameters evolution.
• Mission coordination (Stand-Off/Stand-In collaboration)

The Stand-Off A/C coordinates the mission according to the mission planning performed by the EWOS (EW Operational System) and loaded before the mission.
The coordination of the mission is performed trough a dedicated EW link.
The mission illustrated consists in a defence activity performed by UCAV2 and an attack one performed by UCAV1.

• Real Time planning
The tactical data loaded in the Mission Data Package are the result of several intelligence activity performed some time (maybe hours, days, weeks) before the start of the mission.
The high mobility of modern Weapon Systems can create the risk that this tactical situation could be obsolete when the mission is performed with very negative consequences on the success of the mission.

 

The Stand-Off A/C, after a new assessment of the changed scenario can re-program the mission in real time by allocating a third UCAV to tackle the incoming new enemy attack squadron.
Thanks to its EWAC capability, the Stand-Off A/C will load in real time the new mission parameters in the UCAV3.
